Wouldn't saving and restoring the stack to/from a register (as an array) be as useful?
Yes, but it would be cumbersome if you wanted to support any sort of recursion.

A couple additional functions that would be cool to have

Just throwing out some ideas for some functions that would make really slick additions to Free42: RTN+1 - Return to one instruction after where RTN would normally go, i.e. return and skip the next instruction. This allows creating custom conditional functions. I think the WP-34S has this. PUSHST and...

Flash write cycles

I noticed that the manual mentions the flash chip being rated for a minimum of 100,000 write/erase cycles, and that the FAT is always stored in a static location. What actions on the calculator cause flash writes? Does this only happen when manually saving calculator state or transferring programs v...
